COB

Chip-on-Board (COB) LEDs are arrays of multiple LEDs. Due to the high LED density, they are powerful for their size, making them an alternative option to using individual LEDs.

CQS

The Colour Quality Scale measures 15 colours with a root-mean-square calculated result which is more quantitive than CRI.

CRI

Colour Rendering Index measures the average quality (Ra) of traditional light sources and considered not representative of modern light sources where the use of CQS, TM-30 or TLCI measurements is prefered.

Constant-Current

CC power supplies and drivers regulate their output current to a fixed value e.g. 350mA.

Constant-Voltage

CV power supplies and drivers regulate their output voltage to a fixed​ value e.g. 24 Volts.

DALI

The Digital Addressable Lighting Interface is a lighting control protocol primarily used for static scene setting of commercial lighting systems such as offices, hotels and airports.

DHCP

Dynamic Host Configuration Protocol is used on UDP/IP networks to dynamically assign IP address and other network configuration parameters to each device on a network.

DMX 512

DMX is a standard defining interconnection between lighting controllers and lighting equipment. DMX is primarily used in entertainment and dynamic architectural applications. For DMX pinouts click here
